She has been kept here at an institution for hearing- impaired people after her arrival in the city early this week.
According to an official release issued today, District Collector P Narhari has banned entry of "outsiders" and unauthorised persons into the institution's premises in Gumastha Nagar to ensure Geeta's security.
Those violating this order will face legal action, the release warned.
Geeta will be kept in the institution till her "real family" was found.
She was adopted by the Edhi Foundation's Bilquis Edhi and lived with her in Karachi. She returned to India on October 26.
